More Than Four in Ten U.S. Adults Report Ever Trying Marijuana

Forty-four percent of U.S. adults have ever tried marijuana, according to a telephone poll conducted in July 2015. When the question was first asked in 1969, only 4% of U.S. adults reported ever trying marijuana. The percentage increased sharply from 1973 (12%) to 1985 (33%), and then remained relatively stable until reaching a high of 44% in 2015. The authors note that “[t]he changes over time may reflect either an increase in the percentage who have tried the drug, or an increased willingness to admit to having done so in the past. The latter possibility certainly seems plausible give Americans’ growing support for legalizing marijuana in recent decades” (p. 2). (see CESAR FAX Volume 24, Issue 12, Oct. 26, 2015.) A national survey in 2013 found that the majority of the sampled U.S. adults (58%) believed marijuana use should be legalized (see CESAR FAX, Volume 22, Issue 43).
